Application filed. March 10, 1913. Serial No. 753,429.

To all whom it may concern Be it known that I, AUGUST TABBERT, a citizenof the United States, and resident of Newton, in the county of Jasperand State of Iowa, have invented a certain new and useful Combined CornHusker and Shredder, of which the following is a specification.

The object of my invention is to provide a combined corn husker andshredder of simple, durable and inexpensive construction, wherein aplurality of feed rolls are arranged in pairs in substantially uprightposition for changing the angle at which the crushed stalks are fed tothe shredders cylinder.

A further object is to provide in. such a device a feed platform for thestalks of corn, so constructed and arranged that either end thereof maybe tilted for feeding the stalks to the rollers at different angles andat different heights with relation to the rollers.

A further object of my invention is to provide in such a device huskingrollers arranged in pairs and means for coacting therewith for removingears of corn from the upwardly rotating sides of the adjacent members ofthe different pairs said means being so constructed and arranged as toroughen and partially remove the husks from the ears.

My invention consists in certain details, in the construction,combination and arrangement of the various parts of the device wherebythe objects contemplated are attained, as hereinafter more fully setforth, pointed out in my claims and illustrated in the accompanyingdrawings, in which Figure 1 shows a vertical, longitudinal, sectionalview through a corn shredder embodying my invention. Fig. 2 shows adetail sectional view taken on the line 2-2 of Fig. 1. Fig. 3 shows aside elevation of the right hand side of my improved corn shredder, andFig. l shows a side elevation of the left hand side of the same.

In the accompanying drawings, the reference numeral indicates generallythe frame members of my improved corn shredder, which is preferablyinclosed by side walls 11 and ordinary suitable end members. My cornshredder is preferably mounted on wheels 12 and provided with a tongue13 for transporting it from place to place. The larger part of the rearend of my shredder is covered by a top 14L Suitably mounted in the frameis a shaft 16, on one end of which is a belt pulley 17 or other suitablemeans for operating the shaft 16 from any desired source of power. Onthe shaft, within the shredder, is an ordinary shredder cylinder 18. Just forwardly in the machine from the cylinder 18, are mounted aplurality of snapping rolls 19. The lower ends of the shafts 19 of thesnapping rolls 19 are mounted in the frame member 20, and the upper endsof said shafts are mounted in a frame member 21. The ends of the framemembers 20 and 21 are connected by vertical members 22, which extendbelow the member 20 and are rotatably mounted upon a bearing 23 in whichis mounted a transverse shaft 24-. It will thus be seen that the framein which the feed rolls 19 are mounted is pivotally movable withrelation to the shaft 24.

Secured to the frame member 21 is a forwardly extending curved tooth bar25. The teeth of the bar 25 are held in mesh with the teeth of the gear26 on the shaft 27. On the outer end of the shaft 27 is another gear 28in mesh with the worm gear 29 on the shaft 30, rotatably mounted on theframe of the machine and provided with a suitable crank handle 31. Itwill thus be seen that in the mechanism just described the upper end ofthe frame in which the feed rolls are mounted may be tilted forwardlyand downwardly or vice versa, as desired. Upon the lower ends of therolls 19 are provided gears 32 which are successively in mesh with eachother. The shaft 19 of one of the feed rolls 19 extends below the member20., and mounted on the lower end of said shaft is a beveled gear 33which is in mesh with beveled gear 3 1 on the shaft 24:.

Located forwardly in the machine and below the level of the lower endsof the feed rolls 19, are a plurality of husking rolls 35 mounted on theshafts 36, the upper ends of which are rotatably mounted in a framemember 87 and the lower ends of which are rotatably mounted in a framemember 38. ()ne of the shafts 36 extends upwardly and rearwardly beyondthe frame member 37. Mounted on the upper end of said last named shaft86 is a beveled gear 3.) which is in mesh with a beveled gear 4:0 on theshaft 2%. On the husking rollers are fixed gears 11 which aresuccessively in mesh with each other. The husking rollers 35 extend fromtheir rearward ends forwardly and downwardly in the machine. Locatedabove the husking rollers 85 are two transverse bars or frame members42. Slidably mounted on the bars 42 are a plurality of plates 43.

It will be seen fro.n the above description that the husking rollers 35are arranged in pairs with the adjacent surfaces of each pair rotatingdownwardly and with the adjacent surfaces of the adjacent members of therespective pairs rotating upwardly.

The lower surface or edge of each plate 43 is designed to extenddownwardly beneath the upwardly moving surfaces just mentioned. Therearward edge of each plate 43 is inclined from its upper partdownwardly and rearwardly in the machine, clearly shown in Fig. 1. Oneach side of each of the plates 43 is a roughened or serrated face 44,the object of which will hereinafter be more fully explained. Forsuccessively drawing the plates 43 forwardly and then for moving themrearwardly the following mechanism is provided: Mount ed in the frame ofthe machine forwardly from the shaft 24 is a transverse shaft 45provided with a plurality of cranks 46. The planes in which the variouscranks 46 rest are at acute angles to each other successively. Pivotedto each of the plates 43 is an arm 47, the forward end of which forms asuitable bearing 48 in which one of the cranks 46 is rotatably mounted.

At the forward end of the machine a traveling conveyer 48 of ordinaryconstruction is operated from a transverse shaft 49. One of the shafts36 extends downwardly and forwardly beyond the frame member 38 and onsaid end is a beveled gear 50 in mesh with beveled gear 51 on the shaft49.

Suitable shields 52 and 53 gears 32 and 41,

My improved husker and shredder is preferably built with an adjustablefeedin table 54, shown in 1. The table 54 is provided with downwardlyextending flanges The rearward end of the flanges 55 is provided withopenings which register with each other and receive a rod or shaft 56which is supported in holes 57 in frame members 58 which are secured toor made a part of the frame which carries the feed rolls 19. In theframe members 58 are a plurality of holes 57" so that the rearward endof the table 54 may be elevated or lowered, as desired. Pivoted to theflanges 55, near the forward ends thereof, are downwardly extending arms59. In each arm 59, near the lower end thereof, is a linked slot 60. Athumb screw 61 is extended through the slot 60 and secured in the frameof the machine. TV hen the thumb screw 61 is loosened, the arms 59 canreadily be tilted.

Mounted beneath the hooks or rollers 35 and the cylinder 18 is anoscillating conveyer 62 of ordinary construction, mounted upon shafts 63and 64, which at their ends are pivoted to links 65 and 66 which areprotect the l l l suitably pivoted on the frame of the machine. Mountedin the rear of the machine, with its forward end below he rearward endof the conveyer 62 is a second oscillating conveyor 67 which is ofordinary con struction and is mounted upon shafts 68 and 69 which arepivoted to links 70 and 71, which in turn are pivoted on the frame ofthe machine. Mounted beneath the rearward end of the conveyor 6'7 is acorn re ceiving chute 72, N ear the forward end of the corn receivingchute 72, T have mounted a shaft 73 on which is a fan 74. Rearwardlyfrom the shaft 16 is mounted a transverse shaft 75. Near the upper endof the conveyer 62 and on the shaft 75 is a heater 76 of ordinaryconstruction. The various shafts may be operatively connected asfollows:

On one end of the shaft 24 is a sprocket wheel 77. On the shaft 16 is asprocket, not shown, in line with the sprocket 7 7. A chain 78 travelsupon said sprockets. On the shaft 24 is a belt pulley, not shown, and onthe shaft 45 is a belt pulley 79. A belt 80 travels on the two lastnamed pulleys. On the end of the shaft 16 opposite that on which thepulley 17 is located is a belt pulley 81. On the shaft 7 5 is a beltpulley 82 in line with the pulley 81. A. belt 83 travels on the pulleys81 and 82. On the shaft 24, opposite the end on which the gear 77 islocated is a belt pulley 84 in line with the belt pulley 85 on the shaft73. A crossed belt travels on the pulleys 84 and 85. On the shaft 84 isa cam, not shown, through which reciprocating motion is imparted to theconveyors 62 and 67 through mechanism 87 and 88 which is of ordinaryconstruction. Adjacent to the open end of the corn receptacle 72 is anoscillating conveyor 89 which is operated through mechanism 90, which isof ordinary construction.

In the practical operation of my improved corn shredder, the table 54 isadjusted at its rearward end by means of the shaft 56 which may beplaced in any of the pairs of holes 57 and is adjusted at its forwardend by means of the arm 59. The snapping rollers 19 are tilted at thedesired angle by means of the bar 25 and the mechanism for moving thesame hereinbefore described. The stalks of corn are placed on the table54 and fed through the rollers 19. The crushed ends of the stalks arecaught by the shredder 18 and cut into small pieces. The ears of cornare snapped off the stalks by the rollers 19 and then drop upon therollers 35. The ears usually drop with the butts uppermost and slidedownwardly on the rollers 35. The operation of said last named rollersand the plates 43 serve to strip the husks from the ears and the earsare discharged upon the conveyer 48. The shredded stalks are droppedupon the conveyer 62 and there is usually a smaller amount of shelledcorn which passes through the rollers 19 with the stalks and through therollers 35. The shelled corn and the shredded stalks are conveyed by theconveyer 62 to the lower end of the conveyer 67. The shredded stalks arethen carried to the rear end of the machine and discharged. The shelledcorn is dropped through double openings in the bottom of the conveyer 67into the receptacle 7 2 where light particles and pieces of leaves arefanned out and the corn is discharged to the conveyer 89.

The advantages of a shredder of the kind herein described are numerous.

It will readily be understood that it is desirable to present the stalksof corn to the rollers 19 at different angles, depending upon the sizeof the stalks, the degree of maturity, comparative dryness, moisture andso on. By means of the arrangement of the rollers 19 and the table 54,the stalks may be fed in almost any desired position to the feedrollers. The plates 48 and the mechanism for operating the same assistin removing the husks and also in throwing the ears of corn upon theproper rollers The roughened surfaces 4A assist in removing the husksfrom the corn.
